Mere Christianity brings together what Lewis sees as the fundamental truths of the religion. Rejecting the boundaries that divide Christianity's many denomin-ations, Lewis finds a common ground on which all those who have Christian faith can stand together.

In the classic Mere Christianity, C.S. Lewis, the most important writer of the 20th century, explores the common ground upon which all of those of Christian faith stand together. Bringing together Lewis' legendary broadcast talks during World War Two from his three previous books The Case for Christianity, Christian Behavior, and Beyond Personality, Mere Christianity provides an unequaled opportunity for believers and nonbelievers alike to hear this powerful apologetic for the Christian faith.
